RCOCH3 XX NaOH RCOONa CHX3 NaXH2O a which starting marte

RCOCH3 + X-X + NaOH ---> RCOONa + CHX3 +NaX+H2O

a. which starting marterials are oxidized?

my answer to this is RCOCH3

b. Which starting material ared reduced?

My answer to this is X-X

c. What is the oxidizing agent?

my answer to this is X-X

d. How many electrons are transferred in this redox reaction?

I put one electron for this question; however, I am not sure if the way I approached it is the right way. Some help would be very appreciative. Let me know if my answers to the other questions are correct.

Solution

all are right answers except last i.e d ,

RCOCH3 +2 X-X + 2NaOH -----> RCOONa + CHX3 + NaX + H2O ,

4X converted to 4 X-1 so 4 electrons are required for reduction

hence answer for d is 4
